VALVE.

Application filed April 26, 1920. Serial No. 376,532.

To all whom it may concern:

Be it known that I, IRA E. STUMP, a citizen oi the United States, residing at Cleveland, in the county of Cuyahoga and State oi Ohio, have invented certain new and useful Improvements in Valves, of which the following is a specification.

My invention relates to improvements in valves, and more particularly to that class or type which are designed to be used in connection with main or supply pipes and discharge or service pipes, and in which the flow of fluid between the supply and service pipes is controlled by a main valve, and with which is combined a suitable drain valve and port adapted to be operated and controlled by the main valve so that as the latter is given its initial opening and final closing movements the drain valve will be partially closed and fully opened thereby. By reason of such arrangement and construction of parts, the flow of liquid or fluid therethrough is permitted to pass through the pipes when the main or supply valve is fully opened, the drain ports being then fully closed by the drain valve, and when the main valve is moved to a position slightly above its fully closed position the fluid is permitted to pass from both the supply and service pipes, and when moved to a fully closed position, cutting off the flow 0r fluid from the supply pipe to the service pipe, the drain port is fully opened by the drain valve and, the fluid is permitted to flow out of the discharge or service pipe in order to prevent liquid from becoming frozen within such pipe.

The primary object of the invention is to provide a generally improved valve of the class indicated, which will be exceedingly simple in construction, cheap of manufacture, and eflicient in use.

A further object of the invention is to provide a valve in which the main valve and valve chambers are so arranged and disposed relative to the adjacent parts, and particularly with respect to the bonnet or cap carrying the valve stem, that the fluid or liquid will be eii'ectively prevented from getting into the joints or openings of the bonnet or cap above the main valve and escaping therefrom.

With the above mentioned and other ends in view, the invention consists in the novel construction arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referringto the'drawings, forming a part of this specification, Figure 1 is a side elevation ci a valve constructed in accordance with this invention, the main or supply valve being in its open position, and the drain valve being in its closed position.

Fig. 2, a vertical central longitudinal sectional view taken on line 2-2 of Fig.

Fig. 3, a transverse sectional view taken on line 33 of Fig. 1.

Fig. 4: a longitudinal horizontal sectional view taken on line t4 of Fig. 1.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The valve body 1, may be of any suitable and convenient form, and isprovided at one side with a supply branch 1", adaptedto be connected to a suitable main or supply pipe, and a discharge or service branch 1*, adapted to be connected to a suitable discharge or service pipe, said supply and service branches being separated by means of an intermediate wall or partition 1, adapted to divert the fluid or liquid beneath the main valve hereinafter described and to "form a seat for the same when fully closed.

The wall or partition, 1, is provided with a drain valve chamber 1 tor the reception of the drain valve hereinafter described, and is provided with a drain port 1 adapted to communicate with the service branch 1 when opened, and with a second drain port 1 extendidng to one side of the valve body c for the discharge of fluid therefrom.

The valve body is provided at its top with a cylindrical extension i threaded on its ex terior, said extension or head l being provided on its interior with a main valve chamber l, and it will be observed that the main valve chamber 1 is arrangedimmediately above the drain valve chamber 1 and concentric with the latter.

The bonnet or cap 2, is threaded on its interior to thread upon the extension or head 1 and may be drawn up bymeans of the angular head 2, said cap or bonnet being adapted to carry the threaded spindle or valve stem 3, provided with the usual wheel 4, and carrying at its lower end the main and drain valves 5 and 6, respectively, operating in the main and drain chambers 1 and 1, respectively. V i

It will be seen that, in the present instance,

7 the. main and drain valves 5 and 6, on the spindle 8, are in the specific form of piston valves and, in the present instance, aremade up of suitable layers of packing material secured in position by means of the attach-- ing and clamping nuts 5 and 6*, respectively.

'It will be seen that'the wall or partition, 1, provided with the drain chamber 1 and drain ports 1 and 1 is adapted toform a seat for the main valve 5when the latter is closed, and that when the main valve is closed the flow of fluid is cut off from the supply branch to the service branch, and the respective :pipes connected therewith, and at the same time the relative arrangement of the ports 1 and 1 and the valves 5 and 6 is such that fluid or liquid from the service branch 1 will be permitted to pass through the drain port 1 into the drain chamber, and between the valves 5 and 6,.passing out- 7 wardly through the drain or eduction port 7 same and through. the drain 1 at one side of the valve body.

draining both pipes.

' From the foregoing description, taken in.

connection with the accompanying drawings, theoperation and advantages of my invention will be readily understood.
